FOIDDER SPECIFICATION forming part of Letters Patent No. 341,770, datedMay 11,1886,

Application filed December 3, 1885. Serial No. 184,567. (No model.)

To all whom it may concern:

Be it known that I, PEMBRO E S. RICH, of WVorcester, county ofWorcester, and State of Massachusetts, have invented an Improvement inFodder-Gutters, of which the following description, in connection withthe accompanying drawings, is a specification, like letters on thedrawings representing like parts.

This invention has for its object to improve and simplify theconstruction of feed-cutters.

In accordance with my invention the delivery end of the box of themachine is provided with a metallic throat-piece having a segmentalguide for the blade-carrying lever, the latter having a lip to overlapthe flange of the guide. The throat-piece has an ear or projection toreceive the fulcrum-stud for the lever carrying the blade, the said studhaving applied to it a toothed sleeve to engage a toothed part of thesaid lever, thus permitting the adjustment of the fulcrum of the saidlever, as occasion requires.

The particular features in which my invention consists will behereinafter especially described, and pointed out in the claims at theend of this specification.

Figure l in front elevation represents a feed'cutter embodying myinvention; Fig. 2, a detail of the metal throat-plate detached from themachine; Fig. 3, a sectional detail in the line 0000, Fig. 1; Figs. 4and 5, details of the devices for effecting the adjustment of the end ofthe blade-carrying lever. Fig. 6 is a partial section in the line 00Fig. 1; and Fig. 7, a detail to be referred to.

The wooden frame-work A of the feed-cutter will support at its upper endthe usual box, in which is laid the feed or fodder material to be cutinto small pieces. At one end of the box of the feed-cutter is arrangedthe throat-plate B, made preferably of cast metal, as shown separatelyin Fig. 2. This throat-plate at one end has an ear, I), for thereception of the sleeve b, which is placed upon the bolt [2. The bolt 1)is extended through the slot 0 at one end of the cutter-carrying lever(l, and the end of the bolt beyond the sleeve and ear I) is providedwith a washer, 2, and a nut, 3. As shown in Fig. 5, the sleeve b has atits larger end a flange, b which is cut awayat two sides to i enter agroove, 8, at the inner side of the end of the lever C. One wall, I), ofthis groove is made straight or as a guide, the opposite side beingprovided with teeth 1). One portion of the flange b is made smooth, torest against the wall I), the opposite edge of the flange being toothed,as shown in Figs. 5 and 7, to engage the teeth b To adjust the end ofthe lever 0 up or down, to compensate for wear of the blade or knife, orfor other purposes, the nut 3 will be loosened sufficiently or will beremoved from the bolt far enough to permit the lever O to be movedoutwardly away from the ear b, the wall If and teeth b being removedfrom the flanged end of the sleeve, and thereafter, while the parts areloose, the end of the lever may be raised or lowered, and when in theproper position the lever will be pushed back upon the sleeve in thedirection of the arrow near it in Fig. 4 until the teeth I) again engagethe toothed flange of the sleeve, when the nut will be again screwedupon the bolt 11' sufficiently to draw the bolt tightly into the sleeveto keep the lever upon the flange of the sleeve. In position the sleeveturns in a bearing in the ear I). The opposite end of the throat-plate Bhas a segmental guiding-flange, d, shaped substantially as shown, topresent alip, 5, and, preferably, a rib, 6, as best shown in Figs. 2 and3, and the lever O has attached to it a catch or hook, e, to engage thesaid lip, the

said hook being secured to the lever by a bolt,

0. I have shown this catch or hook as made adjustable by means of anadjusting device, shown as an adjusting-screw, e", the said adjusting-screw and bolt by their movement, as will be readily understoodfrom inspection of Fig. 3, enabling the hook orcatch to be adj usted tokeep the lever O snugly to the rib 6, and to compensate for any wearbetween the hook or catch and the lip 5.

The lever O has connected with itand forming an integral part of it anextension or flange, G, which acts to close the open end of the box andprevent the forward movement therein of the material while the knife orblade 0 is descending through the material.

The knife or blade is adj ustably attached to the lever O by means ofbolts f and set-screws 5 by the lip 12 of the throat-piece, the said lipacting as the stationary member of the cutting mechanism,thecutting-blade 0 being kept closely against the raised lip12, and alsothe lips l3 14, forming part of the throat-piece,

10 by means of the bolt f and adj usting-screwsf.

b, sleeve b the adj usting-lever 0, its attached 1. In a feed-cutter,the throat-piece B, hav-.

I claiming the quadrangular opening, and provided with a segmental guidehaving the lip 5, and

I5 bored at the opposite end to form abearing for the cutter-lever,combined with the cutting-blade 0', the blade-carrying lever to which itis attached, the bolt and nut for attaching the lever to thethroat-piece, and the adjust- 2o able hook e,.carried by the levertoengage the said lip, all substantially as described. 1

2. The throat-piece B, having the ear b, and

the sleeve 6 placed in the said ear and pro-,

vided with a toothed flange, and the bolt b and nut, combined with theblade C and thelever C, carrying it, the said lever beingslotted andprovided with teeth, as at b to engage the toothed flange of the sleeve,substantially as and for the purpose described.

3. The metallicthroat-piece B, having the lips 12 13 14, and thesegmental guide having the flange 6 and lip 5, combined with the boltcutting-blade G, and adjusting devices ff, and with a hook attached tothe lever and engaging the lip 50f the throat-piece, substantially asdescribed.

In testimony whereof Ihave signed my name to this specification in thepresence'of two subscribing witnesses.
